Usage Examples

Private variables

A few private variables are exposed to blocks:

• count the total number of blocks being generated
• index the index of the current block
• start the start number to use instead of zero. Basically index + start

Example:

{{#repeat count=2 start=17}}
  {{> button }}<span>{{@index}}</span>
{{else}}
  Nothing :(
{{/repeat}}

Results in something like:

<button>Click me!</button><span>17</span>
<button>Click me!</button><span>18</span>

Index

Output the index of the current block:

{{#repeat '2'}}
<div id="{{@index}}">
  {{> button }}
</div>
{{/repeat}}

Results in something like:

<div id="0">
  <button>Click me</button>
</div>
<div id="1">
  <button>Click me</button>
</div>
